Police say a video taken by the bystander showed Robert holding down the victim while Angelo punched the victim several times in the face and head.

The victim told 5 On Your Side they then threw him the lake.

"They attempted to drown me while I was attempting to get out," the victim said. I was submerged for like two seconds one time. Extremely weak. Trying to hold on to the rocks. They were going to pull me under and try to kill me.”

The victim said he suffered facial abrasions, a traumatic eye injury and a broken fingertip.

"The fingernail is almost completely torn off. I have bites on the insides of my palms. A swollen left eye," the victim said.

The victim said the recent attack wasn't the first time he's had run-in with the father. He said last year the suspect and another one of his relatives also attacked him over Pokemon Go.

"The Kirkwood police didn't do anything about it after I pressed charges so that was little upsetting," the victim said.

Both suspects are likely to appear in court Wednesday morning for an arraignment. Their bond is set at $15,000 each.
